  • Patent number: 7311938
    Abstract: A method is provided for coating optical lenses and other optical articles with anti-reflection (AR) coatings. The lenses have low reflectivity, provide a substantially white light reflection and have a low stress AR coating and are ideally suited for optical lenses made using a molding procedure which provides a low stress lens substrate. In one aspect the method uses special coating compositions with one being a high index of refraction composition and the other being a low index of refraction composition. In another aspect a method is also disclosed using an optical monitor in conjunction with a conventional vapor deposition apparatus whereby an optical reference lens is used and a particular light frequency of reflected light is measured and this measurement is then used to determine when the desired optical coating is achieved. In a still further aspect the method also preferably calculates the optical thickness of each layer using a specific ratio of blue to green to red colors in the reflected light.

  • Patent number: 6942746
    Abstract: A method of blocking ophthalmic lenses for edging comprises providing an ophthalmic lens having first and second surfaces, providing a first block for securing against the first lens surface and a second block for securing against the second lens surface. The method then includes placing an adhesive layer on the first block, placing a film having cling properties between the adhesive layer and the first lens surface, and urging the first block toward the first lens surface and the second block toward the second lens surface. The film having cling properties provides sufficient bonding force between the adhesive layer and the first lens surface to prevent the ophthalmic lens from slipping in the blocks during edging thereof.
